''Compared to the previous 120-300, IQ has improved in overall sharpness and contrast (especially at wider apertures). This new (S) lens produces good contrast, punchy colours, good sharpness and lovely creamy bokeh (as seen from the review photos here). To my eyes, it is on par with the highly regarded Canon 70-200L f2.8 IS II, and trails closely behind the Canon 300L f2.8 II (losing out in bokeh and slight sharpness). ''

Hmm so maybe they did change something in the design? or may sample variation in the last version be an explanation.

Following their product realignment and QC improvements, Sigma grouped all their lenses into C (Contemporary), A (Art) and S (Sport). New lenses have one of these letters after all the other acronyms. Sometimes they spell it out like 35mm f/1.4 Art.

Why can I not stop looking at this lens. I already have a 100-400L, 70-200 f/4L IS, 70-200 f/2.8L ll and a 300 f/4L IS. Please, no more reviews and no more sample shots of this very tempting thing that I certainly have no need of. Jeez, do I have a problem ?...

Thanks. Got it.

Just saw that there is a huge price difference as well.The 'old' one is selling for about 2000 euro.The new one is being offered for 3500 euro. That is in the Netherlands

In an interview one of the Sigma executives said that the optical formula for this lens is the same as the previous, that this is just an upgrade in the housing.

Maybe the comments on improved performance are comparing this lens with the older non-OS version?If not, then that's very encouraging as the OS version was already very good.

This lens is the cheapest 300f2.8 there is, and it's a zoom. If you don't have the Canon 300f2.8 then this should be a very tempting lens indeed.

Part of the point of the new Sigma is better quality control. I have read quite a few reputable reviews giving this lens exceptionally high marks, some even comparing it to the venerable 70-200L ll. So if all/most new copies of this lens are at least as good as the best of the "old" version, then this will truly be a formidable tool.

I just have to say, it's good to see third-party lens manufacturers stepping up their game. They played the "cheap alternative" for so long that so many people would refuse to buy their lenses due to the cheaper quality. It looks like several of Sigma's new lenses are really starting to rival the kind of quality we get out of Canon's brand-name lenses, even some L-series lenses. That is good competition, and only bodes well for the consumer.
